ment in HeelingMachine Attachments, of

which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. a

The invention to be hereinafter described relates to machines for treating the heels tit) of boots and shoes, and more especially to means'for applying an adhesive to the heel seat prior to the application of the heel thereto.

Tn attaching heels to boots and shoes, nails or other fasteners are usually driven through the heel into the heel seat, and prior to thus securing the heel to the boot or shoe, it is desirablethat an adhesive be interposed between the heel seat and the heel to thus provide a close joint or union between the two.

.To effectively secure the desired results in these respects, the present invention aims to provide means which shall be simple in construction, and so operated during the action of the heel nailing orattaching machine that a fresh surface or film of adhesive shall be automatically presented in convenient and readily accessible position for the operative to apply the same to the heel seat as he pass% the boot or shoe to the heel nailing devices.

The accompanying drawings exemplify one practical form of the invention, wherein a brush is mounted to rotate in abox or tank containing a quantity of the adhesive, and is given 'rotative movement by means connected to the heel nailing devices, so that as the heels are successively-secured to the boots or shoes, the brush is rotated to lift from the tank or box a fresh quantity of the adhesive for application to each heel seat, all as will hereinafter more fully appear.

In the drawings: Figure 1 represents in partial side elevation and section, a portion of a heeling machine containing the present invention; and Fig. 2 is an enlarged section on the line 2--2, Fig. 1. v

For exploitation purposes the invention is shown as applied to a heeling machine of the general type disclosed in the patent of T. G. Plant, No. 958,292 dated May 17', 1910, but it is obviously adapted for use in connection with any machine where heels are attached to boots and shoes.

The machine frame for supporting the operative parts may be of any preferred form or type such for instance, as indicated in the said Plant patent, only so much thereof being illustrated as is necessary to disclose the association of the present invention therewith. side uprights or parts 1, preferably having top flanges 2 which act as guides for side rods or plungers 3, to which the cross-head and heel nailing devices are or may be connected, said rods or plungers having bifurcated lower portions 4, embracing the shaft 5 on which are secured suitable cams 6 actingupon pins or rolls 7 projecting from the side rods or plungers 3, the construction being such that upon rotation of the shaft 5, the cams 6 of which there are preferably two, one at each side of the machine to coact with associated side rods or plungers, will cause the cross-head and nailing devices to be operated substantially as set forth in the said Plant patent to which reference may be had.

Extending from the machine frame is a bracket 8 which may be secured thereto by appropriate means forthe support of a tank or box in which is contained the adhesive to be applied to the heel seat. As shown in the drawing the bracket 8 and tank 9 are inte rally formed, but this is not essential. T e side portions 10of the tank 9 are provided with bearings for the support of the brush shaft 11, and as shown these bearings may be formed by slots 12 in the side portions 10 of the tank to permit ready removal of the brush shaft. To maintain the brush shaft properlv seated in its bearings, hooks 13 are pivoted at 14 to the sides of the tank and have finger portions 15 which extend over the end portions of the brush shaft when the latter is in its bearings.

The brush shaft 11 has secured thereto in any appropriate manner to rotate therewith, a brush 16, the lower portion of which passes into the adhesive 17 as the brush may be ro tated, as will presently appear, and carries a fresh supply or film of adhesive into position for convenient application to the heel seat of a shoe by an operative standing in front of the machine. Securedto the brush shaft The machine frame has the 11 is a ratchet wheel 18 in cooperative relation to a pawl 19 connected at 20 with the pawl operating means, shown as a slide21. Projecting from the bracket 8 at the side thereof is a web or flange 22, the outer end portion of which extends downward at 23 and is perforated at this part to form a bearing for the slide 21. The slide 21 is further guided in its longitudinal movement by passing through a suitable opening in the bracket 8 and flange 24 of the side upright 1, as at 25, and its end, at the right, Fig. 1, projects into the path of movement of a part connected to the nailing mechanism, whereby upon operation of the nailing mechanism as pointed out by the Plant patent hereinbefore mentioned, the slide 21 may have imparted to it movement to cause the pawl 19 and ratchet 18 to turn the brush shaft, and perforce, the brush secured thereto. As an appropriate means to these ends, the side rod 3 which actuates the nailing devices, has adjustably secured to it by means, such as the set screw 26, a collar 27 having a cam projection 28 adapted to meet and force the slide rod 21 to the left, Fig. 1, as the rod 3 descends in operating the nailing devices. The adjustable connection of the collar 27 to the side rod 3 may be made by any suitable means, the-slot 29 and setscrew 26, being a simple andconvenient form of such means.

The end 30 of the slide rod 21 is preferably pivoted to the main portion of the slide rod, as at 31, and is capable of turning upward into dotted line position but incapab of turning downward farther than shown by full lines, Fig. 1, the construction being such that as the side rod carries the cam portion 28 of the collar 27 past the end of the slide it will push said slide longitudinally to the left, Fig. 1, but on the upward movement of the side rod 3, the end 30 of the slide will yield upward without imparting longitudinal movement-to the slide. a

In order to move the slide 21 to the right after having been movedv to the left in the manner stated, the said slide is under the influence of a spring 32, one end of which bears against the part 23 and the opposite end of Which'isseated upon a collar'33 secured to the slide. scribed forms a simple and convenient expedient for operating theratchet through the pawl 19, it is obvious that other means will readily suggest themselves to those skilled in the art for turning the brush 16 by connections with the heel nailing means. In order to prevent rotative movement of the slide 21, a key 34 extends into a suitablekey-way in the slide, and a spring 35 normally acts upon the pawl 19 to hold it in operative re-' lation with the ratchet 18.

The adhesive contained in the tank 9 is, or may be fugitive in character, that is to say, it readily evaporates and becomes thick lVhile the means dewhen exposed to the air, and to obviate this objection when the machine is at rest, a cover '36 is hinged to the supporting bracket at 37 whereby it may be readily turn'ed up 'when the adhesive is to be used and then as readily turned down to close. the tank when the machine is not to be operated, the cover 36 at such times serving to close the top of the tank throughout its length.

From the construction described it will be noted that a simple and efficientdevice is employed, convenient to the hand ofthe operative, for the application of adhesiveto the heel seats of boots and shoes immediately prior to attaching the heel thereto, and that the brush is rotated to expose suitable quantities ofadhesive fresh from the tank by connections with the heel nailing means, and while the described details furnish a good and convenient form of such means, it.

' machine frame to dip into said tank, de-

vices for rotating the brush in its fixed position to expose a supply of adhesive for application to the heel seat of a boot or shoe by the operative at the front of the machine and prior'to attaching the. heel thereto, heel nailing means, and means connected to the heel nailing means for actuating said devices.
